Spacelog Apollo 11

Roger. 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. We're reading you five by. You can go to high bit rate now. Over.

Roger. Going to high bit rate now.

Eagle, this is Houston. Do you read? Over.

Houston, this is Eagle. Roger. Read you loud and clear. How me? Over.

Roger. Reading you five by also, Buzz, and we got the high bit rate. It's looking beautiful through Goldstone. Giving you a count: 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Please give us a count. Over.

Roger, Houston. Eagle with a count. 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Over.

Roger. Stand by. We're reading you five by. Over.

Okay. I'm ready to go S band voice. Over.

Stand by, Eagle. Stand by on step 4.

Columbia, this is Houston. Would you please give us P00 in ACCEPT. We've got a load for you. Break. Eagle, we're ready to go to step 4. Please select S band voice to VOICE. Over.

Hello, Eagle. This is Houston. How do you read—normal voice? Over.

Eagle—Houston, this is Eagle. Read you loud and clear on S band, normal voice. How me? Over.

Roger. You're beautiful in this mode, Buzz. We're reading you five by. Coming with a short count and we'd like one back from you. 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Houston out.

Roger. Houston, Eagle. You're gorgeous also. 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Eagle, over.

Roger, Eagle. This is better than the downvoice backup. Stand by 1

Eagle, Houston. Everybody's happy as a clam with this mode. We'd like to stay here for a little bit. Telemetry looks great, and the; voice is great. Over.

Roger. Understand. I'm checking out camera number 4 now.

Eagle, Houston. Say again what you're checking out? Over.

Roger, Houston. Eagle has checked out both 70 millimeter cameras and both 16 millimeter cameras, and all work fine. Over.

Sounds great. Stand by.

Eagle, Houston. We've looked over your systems on the high bit rate. Everything looks super; we're ready to go. Over.

Roger. Stand by. You want to go back to low bit rate now?

Stand by on that. Over.

Eagle, Houston. We look good through the 210 on this mode. We're going to shift data select to an 85 foot dish to see what we've got, and then we'll be back to you on the 210. If you'll stand by a couple of minutes in this mode, we'll be back with you. Over.

Roger. Eagle standing by.

Eagle, Houston. How do you read? Over.

Houston, Eagle. Read you loud and clear. Over.

Roger. We're reading you five by. We've got the voice good through the 85; the telemetry is in and out through the 85. Stand by. We'll be back with you through the 210. Over.

Eagle, Houston. You can go step 5 now. We'd like low bit rate. Over.

Houston, Eagle. You have low bit rate.

Roger. Copy, Eagle.

Eagle, Houston. Could you give me a short count—this mode? Over.

Houston, this is Eagle with a short count. 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Eagle. Over.

Roger, Eagle. You're five by. This S band voice is really beautiful. Over.

And, Eagle, Houston. We'll be standing by in this mode for a minute or so. We'll be back with you if you'll just stand by. Over.

Roger.

Eagle, this is Houston coming through the 210. How do you read? Over.

Roger. Read you loud and clear.

Eagle, this is Houston. We're happy with all our data in all modes. You can power down the COMM now. Over.

Roger. I understand. Eagle will power down the COMM, and we are just approaching 27 volts now. It looks like we won't have to bother with the high taps.

Right.

We're powering down. Out.

Roger. Copy. Out.

Columbia, this is Houston. We got a TEI 11 PAD for you and an update on the water dump. Over.

Stand by one, Houston. Are you through with the DSKY?

That's affirmative. Over.

Houston, Columbia. Ready to copy TEI 11. Over.

Roger, Columbia. Here we come with the TEI 11. SPS G&N: 37200, minus 060, plus 047. NOUN 33, 098 05 2422, plus 41448, plus 03719, minus 02422. Roll is NA, pitch 020, the rest of the PAD is NA. Set stars are NA. The ullage is two quads—correction, two jets for 16 seconds; use Bravo and Delta. In the comments, the undocked present CSM—correction, this is for—TEI 11 is undocked. Present onboard weight of the CSM is 37200 pounds, about 50 Alfa on your DAP. Over.

Roger. I understand. Waste water dump to 25 percent at 84 hours.

Roger. And, Mike, we'll have LOS in about 11 minutes at 83 44. AOS is 84 30, and prior to—or at LOS, we would like you to go—Configure the S band for high gain track to REACQ, high gain beam to NARROW, and let's try that to see if we can get an automatic REACQ at the next AOS. Over.

Good idea.

I'm in REACQ and NARROW now.

Roger.

Apollo 11, Houston. Also, that water that you got on the aft bulkhead, we—If it's not too much, we just recommend sopping it up and then throwing the sponges away in the waste stowage area. If it's too much, then we recommend using the procedure in the checklist on page F10-14. Over.

Apollo 11, Houston. Would you have Buzz make sure he gives us the OPS pressure readings before you close up? Over.

Will do.

Houston, 11. The OPS read 5750, both bottles.

Apollo 11, Houston. Over.

Houston, Apollo 11.

11, Houston. Roger. Reading you fine, and it looks like the automatic REACQ went very well just as soon as you came around the limb. We have several small items to discuss with you here just before you go to sleep. Over.

Go ahead. Over.

Okay, 11. First of all, on our LM systems checks, everything went fine. I would like to remind you, though, tomorrow you may see an ascent pressure light when you activate the MC&W. There should be no problem, however. You did note that the APS AUX tank pressure was only reading 111 psi, which is normal at this point, but below the level which will trigger your light due to the helium which has been dissolved into the propellant. Over.

Roger. Understand that. Thank you.

Roger. And next item, the supercritical helium rise rate is nominal, and you also had that question for us about your thruster activity during the P22 on the last REV. Believe we understand that now, as you reported that your pitch was in ACCEL COMMAND and your yaw and roll were in RATE COMMAND. You were firing your pitch thrusters. This will couple rates into your yaw and roll axes, and the—You were at that time holding only half a degree deadband and coupling rates into yaw and roll produced the extra firings about the yaw and roll axes. Over.

Yes. That may be true. It's very peculiar coupling, in that it waits longer than you would think and its reaction is greater than you would think. We were getting yaw rates of around four tenths of a degree per second, for example.

Roger, Mike. We did play the data back, and that's the way it looked upon analysis of the chart recordings back here. Over.

Okay. Fine.

They've also looked at the results of your landmark tracking. The marks all apparently were very good, and we've got a full page of data here relative to the altitudes of the various site locations, which I won't read up to you, but I did want to let you know that the marks apparently went very well. I also have your consumable budgets, particularly your RCS propellant quantities. They're Deltas from nominal if you should want them. Your worst quad is quad Charlie, which is 9 percent low. I'll not read up the others unless you want them. Over.

Okay. How about the O₂ fuel cell purge? You want that now?

I'll have to stand by just a moment.

Okay. And then the other one is, we're still charging battery A.

11, Houston. We would like to delay the fuel cell purge until the backside of the Moon, and you go ahead and—should terminate your battery charge at this time. Over.

Okay. Understand. I knew we had another O₂ and H₂ purge coming up in the morning; I wasn't sure whether you wanted to go through with this one or not. I'll wait until the next side and then do it.

That's fine, Buzz.

Terminate battery charging now.

That's right, and one other systems item here—in order to balance your CRYO tanks, would you get your O₂ tank 1 and your H 2 tank 2 heaters off? Over.

Okay. I have O₂ tank heater 1 off, and H₂ tank heater 2 off.

That's right, Mike, and we believe you have your quad Bravo and quad Charlie turned off in your DAP at this time, and a 5 degree deadband. We'd prefer a 10 degree deadband for your sleep period overnight here. Over.

Okay.

One other item relative to a malfunction procedure. It's unlikely that you'll have to worry about this tomorrow, but in your malfunction list under docking on page F11 9, there is a malfunction procedure for a high O₂ flow rate at the top of—under tunnel at the top of page 11 9. We would like to have you not use that malfunction procedure should you encounter the high O₂ flow rate, and instead, check back with Houston for a revised procedure should you find that situation. Over.

Understand, and note has been made in my checklist.

11, Houston. Roger. That just about takes care of all the items we have here on the ground before time to hit the sack, and I guess you will have a presleep check for us before you go to bed.

Roger. We're in the midst of cycling the O₂ and H₂ fans now.

Roger.

And the radiation is as follows: CDR 11012, CMP 10013, LMP 09015. Negative medication. Over.

Houston, Apollo 11.

11, Houston. Go ahead.

Roger. We're thinking about taking the monocular with us on into the LM. We think it might prove to be of some use. Over.

Roger, Buzz. It sounds like a good idea for some of your surveying work there inside the cockpit. Over.

Okay. You want to run that by with whoever might be concerned?

Apollo 11, Houston. We have apparently lost the high gain lock. We would appreciate it if you would give us a help manually to try to relock up on the high gain. Over.

Houston, Apollo 11. ..
